Alphabet Inc.’s Chrome browser could go for as much as $20 billion if a judge agrees to a Justice Department proposal to sell the business, in what would be a historic crackdown on one of the world’s biggest tech companies.

Google’s Chrome browser would be worth a whopping $20 billion on the open market if the Justice Department succeeds in convincing a federal judge to order divestment, according to a report.

Now, Alphabet, Google’s parent company, may be forced to sell Chrome. The browser, which was launched in 2008 and integrates with Google’s search engine, is used today by some 3.4 billion people worldwide.
